add records to a matrix

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

How do I add records to an existing matrix ?
where the elements being passed are variable e.g.

my $sv = "k";
my $sr = "l";
my $sj = "m";

my @X = ([qw(a b c)], [qw(d e f)], [qw(h i j)]);

push @X,[qw($sv $sr $sj)];
[download]

This gives me

a b c
d e f
h i j
$sv $sr $sj
[download]

Instead of what I was hoping for

a b c
d e f
h i j
k l m
[download]

If you take a look at the perlop page, you'll see that the qw operator does not interpolate variables. Therefore, the best way would probably be to eliminate the qw, and change `push @X,[qw($sv $sr $sj)];` [download] to `push @X,[$sv,$sr,$sj];` [download] Hope that helped, -v "Perl.
